Re: Is it possible to extend the model in another application without explicitly changing firs-one?

You should understand that extending a model will create a new table with columns existed in parent in addition to new columns you define , so yes you can extend ..

I want to achieve modularly and loose coupling. Separate responsibility in other words.

and What do you call a extended model ?

By extended model, I mean pat of an existing model, that implemented in one place (in out example app-A) but extended, altered or modified in another please (in out example app-B)

Instance of model1 is accesible in app2, this already means you got your model1 in app2.

Yes, but not the model itself.

But how to add fields to it?

Where to put what:

from appA import model1


class ExtendedModel1(?):
    ?

    new_field = models.CharFiled()

    class Meta:
       ?

Clearly Possible, 

Simply import the model first using appname.models. Hope it helps:)

You can use this as

from appA import model1

in app2

Imagen we have app-A and app-B with model-A and model-B accordingly.

And we want to extend model-A in app-B.

What should be written in model-B to implement it?

In other words, is it possible to implement the same-table extension?
